[Bug 1954469] Re: KVM Bus Lock Debug Exception

2021-12-13 Thread Christian Ehrhardt 
Hi Paul,
Bugs in launchpad are filed against source packages, and "src:kvm" doesn't 
exist for more than 8 years now :-) Instead you'd want to file it against the 
package the code is in, in your case most likely src:qemu [1] or src:linux [2].

Also you should talk about the target Ubuntu release you want the fix to
be in. I assume from the type of bug that you want to feature request
for the coming LTS Ubuntu 22.04 - but please clarify to be sure.

Finally referencing to features/commits works much better if you could
please include the hashes of the commits. Please consider doing so once
they exist upstream. If they are not existing there someone needs to
provide the patches upfront and convince the team that they are stable
enough to be picked up.

The referred kernel version is in the future, so that might be a normal bug for 
a new feature.
I'll re-assign this to src:linux for now as your bug indicates that is the 
target.

You opened a range of bugs in the same pass, other than most others -
this one seems to refer to older qemu/kernel versions. Here you really
need to specify what you'd need where - otherwise all we can do is
consider that already fixed.

TL;DR:
linux 5.13 is in Ubuntu 21.10
